We've seen creative Rickrolls before, but this one takes the cake. Physics student Sairam Gudiseva Rickrolled his teacher by surreptitiously inserting every word of Rick Astley's "Never Gonna Give You Up" into — of all things — a quantum physics essay that still makes perfect sense.

This had to have been tedious work. I can't even begin to imagine what it took to line up each word and still put together a fairly cogent assessment of Niels Bohr's contribution to quantum physics. Needless to say, someone clearly has too much time on their hands. (Not that we have any problem with that.)
